Lets say you bought 50,000 shares at 04 then you have $2000 in it. Now it is at .10
If you sold 20k shares now at .10 you would have your $2000.00 back and have 30,000 "free" shares and that way you can never lose as you have your original investment back. Yes, if it went to $1 you'd only have $30,000 versus $50,000 but it is a safer way to trade.
